Be it known that I, FRANK J.l COOPER, Aa citizen'of the VUnited States, residing at Emporia, in the county of Lyon andState fof Kansas, have, invented certain new and useful Improvements in Rines, of which the following is a specification, reference being had therein to the accompanying drawing. Y .This invention relates to re arms of the rifleV and shot gun type and is intended to provide means wherebythe shell may -be` thrown from the rifle when the breech block isopen.` fr ,i i

@ne of theobjects of the invention is to provide an improved means for throwing the shell from the barrel of the rifle.-k

Another object of the invention is to profr vide an. improved means for operating the V shell v extracting means.

d y Another-object of the i invention is to so construct the rifle thatthe breech block may bedreadilyl removed from the rie andthe `cartridge extracting `means readily removed 35 :the rifle with the breech block entirely open.

placed` in its proper position. -A pocket 17 Y leads-from the cut-outportion 16 and an L- shaped locking'pin 18 is passedvthrough the inner endlportion of the chamber and provided with an operating lmob 19 engagingv a spring 20. This spring normally holdsl the locking pin in the position shown in Fig. 9,'but permits it to be moved `to release the breech block. The forwardportion of this cartridge chamber is providedl with Aa longitudinally extending groove 21 and with longitudinally extending openings V22 and 23 positioned above and extending parallel to the groove 21. This groove 21 forms a track Vin which the cartridge extracting means travels and the slots; 22 and 23 permit arms carried by the cartridgerextracting means to project through thecartridge chamber so that the extractingmeans may be operated bythe breech block. It should be noted lthat this groove is of approximately ythe samedepth as the thickness of the extracting means so that when the reduced end 24 of the barrel 10 is inserted in the cartridge chamber the cartridge extracting means may travel freely in the groove.

Theoartridge extracting means comprises Va body portion 25 having the straight pin 26 extending from one end `and having the hook shaped pin 27 extending from the opposite end and `just beneath the shoulder 28 provided with the cut-out portion 29. It should be noted that 'this shoulder 28 is of suchsize that when the extractor is moved to the forward end ofthegroove 2l it will fit into a notch 30 formed in the inner end portion of the barrel with the cut-out portion forming a continuation of the pocket to receive the flange cfa shell. It will, thus be seen that when the shell isinsertedin the inner end of the'barrel that theflange of the shell will be engaged by the shoulder 28 and, therefore, when the breech block is open and the extracting means moved to the rear end of the groove 21 the shell will be thrown from the gun.

The breechblock 31 is of the general type used in shot guns and is provided .withiai plunger 32 normally held in an extended.,

position by a spring 33 placed about its reduced inner end portion, the outer end ofy the plunger formed in the enlarged head 34 against Vwhich the hammer strikes. vArms- 3'5 and 36 extend from the body lportion ofV the breech block and are provided with openings 37 through which screws 38 may'f be passed for pivotally fconne'cting the'; 4breech block with the forward end portion*l of kthecartridge chamber.v The arml 36 not only serves as a means for pivotally mountl ing the breech block, but is provided with-` fan extension 39 having a hooked end 40 and l provided with a curved shoulder forming a cam V41. The opposite edge of the extension 39 is also curved,`thus forming a kcam 42, the purpose for which will be hereinafter brought out. IVhen this breech block is connected with the cartridge chamber the exten* sion 39 extends-along the side of the chamber between the pins 26 and 27. When the breech block vis closed as shown in Fig. 1 the pin 26 will be engaged by the hook and the cartridge extractor will thus be held at the forward end of the groove 21. `When the breech block is open the cam edge 42 vwill engage the hook shaped pin 27 as shown in Fig. 2 and cause the cartridge extractor to be moved rearwardly until the shell is withdrawn from the barrel and thrown from the chamber as shown in Fig. 3. From an inspection of Fig. 3 it will be readily seen that the heel 43 formed upon the hook 40 abuts against the neck 44 of the pin 27, thus preventing the breech block from being thrown forwardly tofsuch an extent that thehook -40 would be moved out of engagement withy the pin 27. Upon closing the breech bloclr the cam 41 engages the pin 26 and returns. the cartridge extractor to the forward end of the groove, thus permitting the shell to be driven into the barrel by the shoulder 45 of the -breech block. A stem 46 extends from the breech block and is provided with an opening 47 so that when the breech block is closed and the stem passes into the pocket '17 the inner end of the pin 18 may pass through the opening 47, thus holding the vbreech block in a locked position. It is, of

course, obvious that when it is desired to open the breech block that the head 19 must be pressed thus moving the pin 18 out of the opening 47 and permitting the breech block to open. A device has, therefore, been provided which will4 prevent the shell from be-y coming jammed in the barrel'since the extractor is operated whenever breech block is open, thereby driving the shell from the barrel and throwing it from the cartridge chamber. It should also be noted that there is -no `danger of the extractor not operating since lthe operating nmeansforthe extractor forms a part of the breech and, therefore, the breech block cannot be open without the ejector being operated.

"YI-Iaving thus described the invention what is claimed as new, is

1. In a fire arm, a cartridge chamber provided with a longitudinally extending groove, a cartridge extractor slidably mount- `cd' in'said groove, pins extending from said cartridge extractor, a breech block pivotally connected with said cartridge chamber, an arm V-extending from said breech block and Vpositioned between the pins of said cartridge extractor, and the edges `of said arm being curved to `form cams 'for moving said cartridge extractor in said ygroove, upon the opening and closing of said breech block.

i 2. In a fire arm, a cartridge chamber provided with a longitudinally extending groove and with longitudinally extending slots, a cartridge extractor slidably mounted in said groove, pins extending from said cartridge extractor and extending through said slots, a breech'bloclrpivotally mounted uponsaid cartridge chamber, and an arm provided with cam edges extending from said breech block between said pins whereby the cams will engage said pins for moving said cartridge extractor upon'the vopening and closing of said breech block.

3. In a fire arm, a cartridge chamber provided lwith a longitudinally extending groove and being also provided with longitudinallyfextending Vslots npositioned' sub' stantially parallel to said groove, a cartridge extractor slidably 'mounted in said groove, saidVV extractor comprising av body portion, a
